Guidelines for Map Use
Data used to compile this map product is current at the date of publication. Users are encouraged to check the project Metadata record for more recent versions of this map product.
1. Potential habitat mapping is principally derived from historical land resource survey information collected using a range of methods and technologies since the 1960’s. Consequently the accuracy of this data at fine scales may be limited by the resolution of the original data. Site based assessment at an appropriate intensity should accompany use of this map data for all areas. More detail: Potential habitat mapping is derived from Land Unit and Land System Mapping conducted at scales ranging between 1:25, 000 and 1:250, 000. These map products were derived using aerial photography interpretation and digitized on a range of mapping bases between the mid-1960’s and the 1990’s. It should be noted that the potential habitat mapping has an inherent level of spatial inaccuracy associated with the scale and methods of production used to derive the original Land Unit Mapping. These spatial inaccuracies are principally a function of the age of the surveys and the technology available at the time to produce the ORIGINAL maps, the mapping base (topographic or cadastral) on which the original hard-copy mapping was produced and the process of transferring these products to digital media at a later date. The scale of the original mapping was at best 1:25, 000 in parts and enlarging the mapping beyond this scale does not provide further detail.
2. The extent of potential habitat displayed on the map is current at the publication date of the latest available land use data for the region. More detail: Areas of remaining potential habitat were identified by intersecting the most up-to date land-use information to exclude areas of intensive land-use and/or cleared areas now unlikely to support viable potential habitat for the species. Data on the extent of remaining potential habitat is current to 2008 and it is likely that the area of remaining intact viable habitat differs from that indicated on the map. This is particularly true in the peri-urban region of Darwin where current land uses do not reflect the historic mapping of the area. This may result in areas of indicated potential habitat no longer existing or conversely transitional vegetation regrowing after historic land-use changes may provide additional habitat not accounted for by the mapping data (e.g. Inset 1 on map).
3. The map should be used as a guide to identifying the probability that the species is present in any particular area and not a definitive assessment of distribution. The map can be used to assess the risk associated with a particular activity at a location and the likelihood that the activity may result in a significant impact upon a (sub-) population of a threatened species. More detail: The land units and land systems identified as potential habitat on the map represent those most likely to support populations of Stylidium ensatum based on current ecological
Guidelines for Map Use, July 2016 - Stylidium ensatum 2
knowledge at the date of publication. They do not identify all areas where the species may occur and conversely S. ensatum is highly unlikely to occur in all the areas identified on the map as potential habitat. The map should be used as a guide to identifying the probability that the species is present in any particular area and not a definitive assessment of distribution. The map can be used to assess the risk associated with a particular activity at a location and the likelihood that the activity may result in a significant impact upon a population of a threatened species.
4. Highest likelihood of occurrence of Stylidium ensatum appears to be associated with areas of low-lying, poorly drained sandy soil (sandy wetlands) with a water regime that results in free-water or saturated soil moisture conditions at/near the land surface for an extended part of the year (i.e. into the mid-late dry season (August)). These areas have been mapped using historic land survey information and inherent inaccuracies in the mapping data, discussed previously, may result in known locations of S. ensatum falling outside of the potential and most suitable habitat areas. More detail: At a finer spatial resolution, current understanding of the distribution of S. ensatum indicates that the occupancy envelope for appears to be centred on those parts of the landscape where saturated soil profiles (Hydrosols) or free surface water persist into the mid-late dry season (i.e. the parts of the landscape which remain ‘wet’ into July/August). These particular edaphic conditions are further limited by what appears to be a preference for low-nutrient, sandy soils somewhat atypical of low-lying topographic positions and wetlands in the Top End. A buffer was not applied to the boundaries of the potential habitat polygons in this instance as the potential habitat is considered to significantly limit the likelihood that the species occurs beyond the boundaries of these polygons and is more likely to be restricted to core central areas within the potential habitat where water persists in the landscape for longer periods. Currently available spatial information regarding water body persistence and regolith composition does not correlate well with the hypothesised distribution of the species. Consequently, a precautionary approach was adopted in identifying areas of highest likelihood of S. ensatum occurrence and all potential habitat was considered of uniform significance in his assessment. Consequently, occurrences of S. ensatum, may fall outside the mapped areas inferred as most likely support the species as a result of issues associated with inaccuracies in the potential habitat mapping and site-scale variations in habitat conditions and/or error associated with the positional accuracy of the species record. As with any natural resource spatial product, it is recommended that this information be used as a guide to the most likely areas in which S. ensatum may be encountered and should be accompanied by appropriately timed field survey to clarify the presence or absence of the species from a particular location more definitively.
5. Confirmed absence locations represent detailed floristic survey sites sampled at an appropriate time of year where Stylidium ensatum was not recorded. More detail: Targeted search locations (absence) data are full-floristic sites sampled within the expected distribution of Stylidium ensatum over a number of years between June and August. These sites represent locations sampled at an appropriate time of year where S. ensatum was not recorded and collection data suggests the species should be present and most detectable. Surveyed sites were largely sampled using a standardised methodology (Brocklehurst et al. 2007) by experienced NTG botanical staff and represent the best available information on the known distribution of the of the taxon within the Darwin Region. This does not definitively imply that the species was not present at the location given the cryptic life history of the taxon and the seasonal conditions at the time of sampling. However, it can be considered to represent the temporal ‘window’ of maximum-likelihood that the species would have been detected if it was present at the time of sampling.
6. ‘Point’ data on the occurrence of S. ensatum represent vouchered individual specimens or discrete locations at which the species has been recorded in the field.
Guidelines for Map Use, July 2016 - Stylidium ensatum 3
7. Mapping reliability (Confidence Rating) has been assigned to areas in which varying intensities of field assessment have been undertaken or are considered to represent suitable habitat for the species. These generically range from ‘High’ being high-intensity, targeted, species specific surveys or areas in which confirmed sub-populations are known to occur through to ‘Low’ where reconnaissance level or incidental surveys have been undertaken or habitat is considered unsuitable. More detail: In the broader regional context (represented on the location map) areas within the greater Darwin region where appropriately timed general surveys have not encountered the species are considered a moderately reliable indication of species presence/absence based on the intensity of field data collection. At the finer scale within the Extent of Occurrence (EoO – represented by the inset maps), the confidence levels have been combined with the potentially suitable areas (i.e. highest likelihood of occurrence) to give an indication of the confidence in not only the level of survey undertaken, and therefore, the presence/absence of the species, but also the presence of habitat suitable for the species. Areas where targeted surveys have been undertaken are considered highly reliable, whereas areas of low reliability within the EoO are indicative of unsuitable habitat (e.g. wetlands or built up areas)

Guidelines for Map Use, July 2016 - Stylidium ensatum 5
Population status of Stylidium ensatum (July 2016)
Sub-population Reference no Status Size Trend Pressures Uncertainties Current Knowledge State
1 Lee Point
Extinct? Unknown – likely
extinct Demonstrable
decline Weed incursion Extent and status of the sub-
population unknown – likely to be extinct.
Extensive searches at the correct time of the year have not relocated this sub-population in recent years. Previously recorded locations are now dominated by invasive exotic species which are highly likely to outcompete S. ensatum at these locations.
2 Shoal Bay Conservation Reserve
Unknown Unknown Unknown Management Weed incursion
Geocode precision for collection unlikely to be high. Current status of sub-population, unable to be relocated in area to date. Longer-term security and viability of sub-population.
Only one individual confirmed during inspection for subdivision (EcOZ, 2015). Current status of sub-population unknown.
3 Giraween Road
Extant <100 individuals
Unknown Management Weed incursion
Mechanisms for conservation on-site given potential development unknown at this point in time.
Additional sub-population located in 2014 Well documented and identity verified. Large sub-population, uncertain if connected with Noonamah South?
4 Mc Minns Lagoon
Unknown Unknown Unknown Adjacent development Management Weed incursion
Geocode of collection appears incorrect
Population unlikely to be extant at location if the original geocode was correct.
5 Hayes Creek
Extant <100 individuals;
patches vary
Unknown Management Mechanisms for conservation on-site given potential development unknown at this point in time.
Relocated in 2014 in the vicinity of the original collection by S.T. Blake in 1946. Identity verified. The geocode for the S.T.Blake collection is assumed to be the same as the 2014 collection location.
